作者为了研究全身振动与视机能的关系,将兰氏(Landot氏)环的大岛式近距离视力表,与近距离的平假名字母视力表一起固定在振动台上。振动台是在等密尔线的条件下,对8名年龄为21～23岁、视力正常的大学生,进行了靜止的视力减退的实验。并且还对1名被检者进行了眼球的视标追迹移动的观察。在此基础上,与有关人体加振的视力减退进行了比较性的探讨。视力减退是以视效率(振动负荷时的视力/无负荷时的视力)作为指标加以阐述的。其比较结果为: 1.在视标加振时,对于两种视标视力表所测定的视力减退,均是随着振动密尔值的增大而视效率降低。并且不同的振动颊率的视效率,均在1～
In order to study the relationship between total body vibration and visual function, the author fixed the large island-like short-distance eye chart of Lands’ ring on a shaking table together with a short-distance hiragana alphabet. Shaker is in the condition of the Mill Line, 8 of 21 to 23 years old, normal vision college students, carried out a static vision loss experiment. One subject was also observed for visual target tracking movement of the eye. On this basis, a comparative study was conducted with eyesight-reducing related to human being’s vibration. Vision loss is based on visual efficiency (visual acuity during vibration / visual acuity during no-load) as an indicator. The comparison results are as follows: 1. When the vibration of the optotype is increased, the visual acuity decrements determined by the two visual acuity tables are decreased with the increase of the vibrational multivalue. And the visual acuity of different vibration cheek rate, are in 1 ~
